Knapsack: pack pages into data URIs.

What is Knapsack?

Knapsack is a simple web service that takes a URL, pulls down the resource and
all the resources it references, and 'compiles' them into a data URI. What's
interesting about a data URI is that you can bookmark it and access it offline.
This can be really useful if you have a device that has an intermittent net
connection (an iPod Touch, for instance).

It works a lot like Hixie's Data URI
Kitchen, but it preserves
images, stylesheets and external javascript libraries.
